To be able to use S7-SoftPLC with PROFINET® IO via SoftNet PN IO 2006, the following steps have to be made.

  • SoftNet must be installed and licenced on the computer.
  • The computer must have a static IP address.


Station Configuration Editor

  • In the Station Configuration Editor an application is inserted on index 1.


WARNING: THE STATION NAME MUST BE IDENTICAL WITH THE NAME OF THE COMPUTER.


  • On index 3 a component of the type "IE general" is inserted. In the parameterisation, the network controller for use with PROFINET® has to be selected.
  • In the dialog "component properties" verify the network settings.

(The box "Activate ISO protocol only" must be unchecked.)


SIMATIC® Manager (STEP®7 v5.4 SP1 or better)

  • The PG/PC port must be set to TCP/IP.
  • A SIMATIC® PC-station is inserted into the project.


WARNING: THE STATION NAME MUST BE IDENTICAL WITH THE NAME OF THE COMPUTER.


  • Start the hardware configuration.
  • An object is inserted on index 1.

Right-click on index1 >> Insert object >> User application >> Application >> SW V6.3

  • An object is inserted on index 3.

Right-click on index 3 >> Insert object >> CP Industrial Ethernet >> IE general >> SW V6.2 SP1...

  • In the dialog "Properties – Ethernet port IE general" the computers static IP must be entered and networked with the new subnet.
  • With a right-click on IE general >> Insert PROFINET® I/O system a new PROFINET® network is created.


Add I/O nodes to PROFINET® IO network

  • With a right-click on IE general >> Edit Ethernet nodes, the following dialog appears.

  • The button "Browse..." allows to search for available PROFINET® nodes.
  • A unique name has to be assigned to every PROFINET® node.

After a node was loaded into the dialog via "Browse...", a name for the node can be entered in the text field "Device name" and can be assigned to the node by clicking on "Assign name".


WARNING: THIS NAME HAS TO BE UNIQUE IN PROFINET® NETWORK. THE NAME IS NEEDED LATER DURING CONFIGURATION.


  • Now a PROFINET® node can be assigned to the PROFINET® network.

The node is added from the catalog to the network via drag & drop.

  • After a right-click on the node >> object properties, the following dialog appears:

  • In "Device name" the same name has to be set, as it was assigned in "Edit Ethernet member".


WARNING: THE NAME OF THE DEVICE HAS TO BE IDENTICAL WITH THE ASSIGNED NODE NAME FROM ABOVE.


  • The individual I/O slices of the node must be configured correctly, otherwise no communication to the node can be established.


Completing the hardware configuration

  • The hardware configuration must now be compiled and downloaded into the PC-Station.


NOTE: THE BUS STARTS AFTER 30SEC, WHEN THE I/O'S ARE TRIGGERED BY THE APPLICATION.


Avoid unnecessary CPU load:

SoftNet PN I/O is a software driver that needs system resources. In order to get the system to high-performance, the following should be noted.

  • Close not needed services
  • Set SIMATIC® NET IEPG Help Service to  "Deactivated" from control panel services
  • Remove the station manager from the StartUp (Start menu)

The service "Simatic Net Station Manager (s7wnsmsk.exe)" has reserved the port 102 (iso-tsap) for itself, so SoftNet PN IO can not be run in combination with CP343/443 Emulation (Cpx43), because it needs the port 102 as well. If the service "SIMATIC® Net Station Manager (s7wnsmsk.exe)" is deactivated, PROFIBUS® IO will not work anymore.


Typical errors:

  • Siemens "Station Configuration Editor" looses the network controller.


Help:

  • Start the Station Configuration Editor
  • Insert the network controller
  • Close the Station Configuration Editor
  • Start the Station Configuration Editor again
  • Remove the network controller (now it knows, that the controller is no longer available)
  • Insert the network controller again (The controller is ready now)
  • Close the Station Configuration Editor
  • Reload the configuration with SIMATIC® NCM PC Manager


Using SoftNet PN IO in S7-SoftPLC

SoftNet PN IO can be accessed from the PLC-program via SFC14/15 SFB52/53 only. The parameters LADDR, ID and INDEX do correspond to the PROFINET® address from the hardware configuration.
